Line Up and Wait
After having to cancel my reservations for Oshkosh as everyone canceled on me a week ago I decided to go anyway and then my old college room mate from 48 years ago decided to go along. So I had my Avidyne 540 updated with the recent 10.2.3 update and that wiped out our personalized settings for the data displays. Tonight I updated my Nav and Obstacle databases and re-entered my personal choices for Screen display Data. I thought it a good idea to add outside air temperature and it gives me a choice of TAT or SAT. I assume TAT is True Air Temp. but what is SAT? Only thing I can think of is Sadistic Air Temp after last week. Probably head slapping simple but I've got nothing. What is the S for?
